The 81A-7102 2nd gear was the original design for these type gears. It uses a sleeve inside the bushing and a pin in the main shaft to hold it all in position. A change to this type gear may require a change back to the old style main shaft. The 51A-7102 was used after the war and they are harder to find NOS. It might be time for a change unless a person can come up with the later part. The early style might work well in deceleration but I don't know if it would be any better or not.
